Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
SAP NetWeaver Enterprise Portal OBN does not perform proper authentication check for a particular configuration setting. As result, a non-authenticated user can set it to an undesired value causing low impact on integrity. There is no impact on confidentiality or availability of the application.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

SAP NetWeaver Enterprise Portal OBN (Online Business Navigation) feature lacks proper authentication validation when modifying a specific configuration setting. An unauthenticated attacker can set this configuration to an unintended value, resulting in low-impact integrity compromise while confidentiality and availability remain unaffected.

MitigationApply SAP security patches for CVE-2025-23194 and review OBN configuration settings to enforce authentication checks. Verify that unauthenticated requests cannot modify configuration parameters.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify SAP NetWeaver Enterprise Portal installation
    Check the SAP system for NetWeaver Enterprise Portal components. Use transaction SM51 to list installed server instances, or inspect SAP MMC (Microsoft Management Console) for Enterprise Portal processes. Look for SAP Enterprise Portal or EP configuration in system landscape.
    Affected if The system is running SAP NetWeaver Enterprise Portal without the CVE-2025-23194 patch applied
  2. Verify OBN feature is enabled
    Access SAP NetWeaver Enterprise Portal administration (via System Administration > System Configuration > Service Configuration or similar). Look for OBN (Online Business Navigation) configuration area. Check if the OBN service is active in the portal's system landscape directory.
    Affected if OBN feature is enabled and accessible without authentication checks on the configuration endpoint
  3. Inspect OBN configuration authentication settings
    Navigate to OBN configuration in SAP Enterprise Portal admin console. Examine settings related to authentication validation for OBN configuration modifications. Look for parameters controlling unauthenticated access to configuration change operations.
    Affected if Configuration allows unauthenticated modification of OBN settings or lacks authentication enforcement on configuration update endpoints
  4. Test unauthenticated configuration modification
    If permitted by policy, send an HTTP request to the OBN configuration endpoint without authentication credentials. Observe if the request succeeds and returns configuration data or accepts changes. Check HTTP response status and any configuration parameters exposed.
    Affected if Unauthenticated requests can successfully modify OBN configuration parameters or receive valid responses from configuration endpoints
  5. Review OBN-related web services and ICM logs
    Examine SAP Internet Communication Manager (ICM) logs and OBN-related web service endpoints. Look for requests to OBN configuration URLs without session credentials. Use transaction SMICM or log files in /usr/sap/<SID>/D<instance>/work/.
    Affected if Logs show unauthenticated access attempts or successful requests to OBN configuration from external IPs without valid authentication tokens

The environment is affected if SAP NetWeaver Enterprise Portal with OBN feature enabled allows unauthenticated modification of OBN configuration settings, resulting in potential integrity changes to the portal configuration.
